Morgan is of course being sarcastic. It would of course be true a 2170 cell would weigh more than a pouch cell.
But this doesn't take into account what else has to be done to finish the "battery" build.
A fragile plastic bag needs a lot of protection, where as a metal cylinder doesn't need as much.
The bottom line is how far will bike A go vs bike B.
The question will be if the 3 brands are riding at the same speed on the same road which one will go farthest?
A really light aero bike could go farther with a smaller battery than a heavy upright brick of a bike with a bigger battery.
I'd love to see a Damon HS vs a Ego+ RS vs a Zero SRS (with power tank and all battery pay walls dropped) in a side by side range test.
Maybe next year we could do that.
